As we get older our diet doesn't give us what we need as far as vitamins, minerals and supplements. I strongly recommend anyone over about 40 take a multivitamin every day or two. You'd be surprised what issues it can head off.
As we age, it gets more and more important. Some companies offer daily supplements labelled as 50+, and if you're close to or over that age, they are highly recommended.
MM's case baffles medical science. I will talk to a witchdoctor colleague and see what can be done. I think I saw something in a James Bond movie that might work...
